Seems that all Xperia X modes use common a vendorId, so it would be possible to catch them all with a single rule (hoping that the user doesn't have another Sony device at the same time to which they son't want to give full access).

We can now built a nice 90-xperia.rules ready to by dropped inside /etc/udev/rules.d/ :

Thanks for the link!
I added an disclaimer on the top of the guide, but this one is still useful for those that already unlocked their bootloaders before 34.3.A.0.228 came out since jolla still wants you to use windows in that case.

Cause it mismatches the one given on website (tested both .7z and .tar) and is bit worrying tbh. I used the torrent download and trying to download the one from uploaded.to, but it says not available for the moment, pay me crap. Can anyone check if they have mismatching file too?

I guess not many ppl check these things at all and uses it regardless...

Im quite surprised, there has been few others wondering same thing here, but hasn't raised any flags either!

Edit1: Finally finished download from uploaded.to and same mismatch.

Edit2: Well, I just cloned the git and compiled it myself from sources, just in case!

Edit3: Well bloody hell, even the build files dont work anymore, following build instructions, you wont get final .JAR file. Its missing something, even that has been asked about in issues, without any answers. Its like the project is abandoned by dev...
